But unfortunately, there are those who have a similar error simply ignores and continues to operate the car, can be reduced!

Engine fault diagnostics system on Renault Logan

The engines on all cars Renault Logan are an technologically complex system with their own side computer, which is capable of identifying the presence of a malfunction from all sorts of sensors and ending with a whole chain of systems.

All you understand that all errors and causes of faults, it will not be able to lay out on any onboard computer, therefore, in order to notify the driver about any critical breakdown, the very icon of Check Engine lights up.

At one time, errors can wear not the fatal nature of the malfunction, when how skipping it out of sight, you can miss more serious breakdown. As you know, two times the same light will not be able to light up. If you do not pay attention to the error message in time, then.

It follows from this that the "Check" signaling lamp, you need to diagnose and delete as soon as possible.

We learn the reason for the air of the check and delete the error

When the lamp lights up immediately after turning on the ignition, and immediately goes out - it's not a breakdown! Do not confuse!

For such manipulations, Renault Logan cars are equipped with a trapezoidal 16-pin-and-II diagnostic connector, which is located in the glove compartment.

In order to determine the error of the system you can take advantage different ways Diagnostics:

• A visit to the specialized car service, with the ability to diagnose and output errors in special codes with decoding. Keep in mind that the price only for diagnostics may exceed 1000 rubles, regardless of what type of malfunction.
• Buying an on-board computer that is capable not only to read all the errors, explain their cause, but also to remove from memory if necessary. Similar devices on Renault Logan are installed in the place of the central duct or at any convenient place. windshield. It is worth noting that the acquisition of such BC will cost the owner within 4000-5000 rubles. (This option is not the worst, since the functionality in such devices is quite wide).

  One of the options for installing an abnormal side computer on Renault Logan. Plus - Easy installation, minus - greatly attracts the attention of "Marauders"

• Purchase a special OBD2-BT scanner (in popular Chinese online stores) or in the stores of the city, to use one smartphone and a special program to be considered, determine and clear all errors of the car system. This device is compact enough and mobile, fixed in diagnostic connector And with Bluetooth connects with the phone.

  Most optimal option For price / quality - diagnostic adapter ELM327. Together with a cell phone allows you to completely replace the regular on-board computer

The device is capable of anywhere and in the minimum time to establish the cause of the malfunction.

P0420 Catalyst System Efficiency Below Threshold (Bank 1) / The efficiency of the catalyst system below the threshold is one of the most frequent errors Renault Logan, which leads to the appearance of the "Check engine" icon. Most often occurs when refueling low-quality fuel!

The easiest way to remove the "temporary" check

The easiest and most fast way Reset the error will be the removal of the terminal with the battery. However, this attempt will only hide the consequence of the emergence of a malfunction, but will not open its causes, and after some time "Check" will light up again.

Real sellers of cars, who try to hide the obvious drawbacks of their cars, are used by such admots. More.

RESULTS

In any case, what kind of options you have chosen as a result, it is the diagnosis of a fault of the check lamp "Check" on Renault Logan, will help you to identify the true reason for its appearance. And the sooner you get rid of it, the more reliable the next kilometer of your path will continue.

For each car, including the Renault Duster, it is extremely important that all nodal units work in a clear and well-coordinated mode. This rule, first of all, refers to the functionality of the engine.

Control the operation of various nodes and car elements The driver can visually on various testimony of control devices located on the instrument panel. If a few decades ago, the owner of the car had to look after and listening to determine how the engine works, today the correctness of the main unit operation can be easily monitored by a special indicator.

Almost everyone modern car equipped with such a check signal as Check Engine. If it is literally translated, then this term means "Check engine". In the perfect version, the "Check" light should light up at the start of the engine and go out after a few seconds.

In the case where the indicator does not go out or, on the contrary, it turns on during the movement of the car, you should think about the diagnosis and then in a specialized car service. Activation of the check indicator sometimes scares beginner motorists. You should not be afraid of this "assistant", because it is he who will directly indicate a possible malfunction, which means to protect the movement.

Why does the indicator light up?

Burning Light Check Engine may indicate various car malfunctions. But, as practice shows, the most common of them are:
Bad fuel;
insufficient level oils;
Ignition Candles Malfunction;
incorrect operation of the ignition coil;
faulty lambda probe;
Catalyst failed exhaust gases;
bad nozzles;
Balanced gas station and / or clogged fuel filter;
Not a hermetic cover fuel tank;
Fault high voltage wires;
FEDERATED DMRV

Methods of correction

The fact that the "Check" indicator itself should alert the driver during the movement of the car, because it is an unambiguous signal in order to sign up for the diagnostics in the autotech center to identify and eliminate possible faults. But if the auto owner has sufficient experience, skill and skills, then a number of faults can be eliminated independently.

Low fuel levels, as well as poor quality gasoline is the most common cause of the indicator ignition. In this case, it is recommended to completely drain the poor-quality fuel from the gas tank and again completely fill the car with high-quality gasoline.

With low oil - everything is simple. Using the probe, the level is checked and the required quantity fills.

The main element guarantees sunbathing fuel mixesare ignition candles. In case of malfunction, at least one candle, the correctness of the car is not guaranteed. It is necessary to thoroughly inspect all the candles, if necessary, remove the tart from them or simply replace. You can only change the ones that are faulty, but the professional vehicle is recommended to change the entire set immediately to avoid possible trouble in the ignition system. The timely replacement of one or several candles will be the key to the correct operation of the catalyst of the exhaust system and the engine of the car.

If there are suspicions that the reason lies in the ignition coil, it is necessary to check for the presence of spark and resistance at the output.

In the event of a malfunction of the oxygen sensor (lambda probe) there is only one output - replacement of spare parts. It is part of the exhaust system and is partly responsible for controlling the fuel consumption. The fact is that after a certain period of time, the sensor can be covered with a layer of oil soot (spent motor oil), and therefore its testimony no longer possess the original accuracy.

The purpose of the catalyst is to transform exhaust to a cleaner gas mixture. Not only the check indicator indicates its fault, but also the engine capacity has almost two times. In order to change the catalyst, you will have to initially remove the muffler. As a rule, such a breakdown is characteristic only for cars with impressive mileage.

The popular reason for faulty nozzles is low-quality fuel. Injectors are only replaced.

Gasoline pump I. fuel filters very often cause damage power aggregates car. As a rule, these elements, and especially fuel filters for diesel engines Renault require full replacement.

The disturbed tightness of the fuel tank cover is also often the cause of the ignition of the bulb "Check". If the cover is not tightened enough or on its surface there are chips, cracks, or other defects, then the air pass will begin, which will invariably lead to increased flow Fuel.

The air consumption sensor is responsible for adjusting the amount of incoming air required for ignition. Faults of this element can lead to incorrect consumption of gasoline, to an increase in carbon dioxide in exhaust system, reduce the power of the motor and the smoothness of the car movement. Requires replacement. For a long time to maintain the sensor in good condition, you should not forget about the periodic replacement of the air filter.

If a high voltage wires They have bad insulation, it will also reflect on the work of the car as a whole. In this case, the ECU recognizes a malfunction and an alerting of the check indicator checks. As a rule, it is necessary to completely replace the wires to eliminate.

Gadgets for diagnostic

In order to independently identify the cause of the engine troubleshooting, you can also additionally use one of the two proposed options.

Purchase on-board computer capable of not only to consider all working errors, but also to decipher them, as well as if necessary, periodically delete them from your memory. Such gadgets are usually installed on any, convenient location for the driver near the windshield, but most of the car owners choose the point of the central duct.

Buy a special scanner to read using a computer program and an ordinary smartphone, to determine and decipher possible errors in the work of important velocities of the car. The scanner has a compact size, is quite mobile. Its fixation is possible by means of a standard diagnostic connector, and the connection to the phone is performed via Bluetooth.

Thus, the Check Engine light is the control indicator, with which you can track the correctness of the operation of almost each engine element. Therefore, it should be treated extremely carefully.

Very often, the car owners ignore this signal, naively believing that the cause of fire lies only in the use of poor-quality fuels, and therefore simply temporarily disconnect rechargeable batteryso that the indicator goes. But this is not the way out of the situation. Such a disregard may subsequently lead to serious engine breakdowns and to his forced overhaulthat is very expensive.

Therefore, it is more expedient with the indicator signal to call in the nearest car service for diagnosing, identifying and timely eliminate possible problems. Only in this case, and then you can exploit your car with a sense of complete confidence and security in its work.

Attentiveness and timely repair is a pledge of a comfortable movement that increases with each kilometer traveled.
